try SystemProcessorInformation and SYSTEM_PROCESSOR_INFORMATION (instead 
of SystemCpuInformation and SYSTEM_CPU_INFORMATION) and you'll see that 
it's not Wine specific. so you cannot extend them

moreover, don't trust MSDN... they're simply saying that if there's the 
same API in kernel32 it should be prefered over it's ntdll counterpart...

regarding your patch, the core of the work has to be done in ntdll. you 
just have to find the correct API in ntdll that does the job
you're not using the right one (at least for the class of the query)
for example, SystemNumaProcessorMap could help you... (even I coudn't 
find some docs about the structures, but I didn't search a lot), and 
reverse engineering (using ntdll as a blackbox) may be of some help
